I live with my older brother who travels a lot and my sister-in-law Ryoko. For me, who likes older women, living with Ryoko without an older brother is a painful story that stirs delusions. Especially after seeing Ryoko's violent dementia while peeping into the sex of her older brother and his wife before going on a business trip. The cute face is distorted and it feels violently, it gets hot and wet over there, and the intense feeling, and the appearance of Iki violently invites delusions.
